Key Calculus Terms and definitions covered in this textbook
• Arccotangent function

See Inverse cotangent function.

• Binomial theorem

A theorem that gives an expansion formula for (a + b)n

• Coefficient of determination

The number r2 or R2 that measures how well a regression curve fits the data

• Coordinate(s) of a point

The number associated with a point on a number line, or the ordered pair associated with a point in the Cartesian coordinate plane, or the ordered triple associated with a point in the Cartesian three-dimensional space

• Data

Facts collected for statistical purposes (singular form is datum)

• Direction vector for a line

A vector in the direction of a line in three-dimensional space

• Geometric sequence

A sequence {an}in which an = an-1.r for every positive integer n ? 2. The nonzero number r is called the common ratio.

• Imaginary part of a complex number

See Complex number.

• Independent variable

Variable representing the domain value of a function (usually x).

• Limit

limx:aƒ1x2 = L means that ƒ(x) gets arbitrarily close to L as x gets arbitrarily close (but not equal) to a

• Linear equation in x

An equation that can be written in the form ax + b = 0, where a and b are real numbers and a Z 0

• Linear function

A function that can be written in the form ƒ(x) = mx + b, where and b are real numbers

• Magnitude of a vector

The magnitude of <a, b> is 2a2 + b2. The magnitude of <a, b, c> is 2a2 + b2 + c2

• Mathematical induction

A process for proving that a statement is true for all natural numbers n by showing that it is true for n = 1 (the anchor) and that, if it is true for n = k, then it must be true for n = k + 1 (the inductive step)

• Quartic function

A degree 4 polynomial function.

• Sinusoidal regression

A procedure for fitting a curve y = a sin (bx + c) + d to a set of data

• Speed

The magnitude of the velocity vector, given by distance/time.

• Statistic

A number that measures a quantitative variable for a sample from a population.

• Tangent line of ƒ at x = a

The line through (a, ƒ(a)) with slope ƒ'(a) provided ƒ'(a) exists.

• Upper bound for real zeros

A number d is an upper bound for the set of real zeros of ƒ if ƒ(x) ? 0 whenever x > d.
